기능성 음성장애의 병태생리

진성민,Jin, Sung Min 대한후두음성언어의학회 2014 대한후두음성언어의학회지 Vol.25 No.2

기능성 음성장애는 후두에 구조적 혹은 신경학적 병변이 없이 음성발성에 장애가 있는 질환으로, 의학적인 부분만으로 설명하기가 어려운 장애 요소들을 내포하고 있기 때문에 진단에 많은 혼란이 있을 수 있는 논쟁의 여지가 많은 음성질환이다. 기능성 음성장애의 중요한 부분 중의 하나인 muscle tension dysphonia는 후두 근육과 후두 주변 근육의 지나친 긴장에 의해서 발생하는 음성장애로, 비록 후두 내/외근의 운동이 제대로 조절되지 않는 것이 muscle tension dysphonia의 가장 첫 번째 원인이라고 알려져 있고, 특정의 개인적인 인성의 특징(personality traits)들도 발생에 있어서 상당히 중요한 부분을 차지 하는 것으로 연구되고 있지만, 이들 근육이 도대체 어떻게 문제가 되는 지에 대해서는 사실 아직까지 완전하게 설명하기에는 곤란한 점이 많다. 또한 최근 들어서는 muscle tension dysphonia를 하나의 질환으로 보기보다는 기능성 음성장애의 문제점들을 설명하는 진단적 지표(diagnostic label)로 보는 경향이 많으며, 기능성 음성장애와 기질적 음성장애(organic voice disorder)를 아우르는 위치에 있는 것으로 해석하는 경향도 있다. 따라서 기능성 음성장애에 대한 분류나 발생기전에 대한 의견들은 아직까지 논란이 되는 부분들이 많은 상태이고, 기능성 음성장애를 더 잘 이해하고 이 질환을 성공적으로 치료해 나갈 수 있는 중요한 요인들을 찾아낼 수 있도록 더 많은 연구들이 이루어 져야 할 것으로 생각된다. Functional dysphonia refers to a voice disturbance that occurs in the absence of structural or neurologic laryngeal pathological characteristics. Poorly regulated activity of the intrinsic and extrinsic laryngeal muscles is cited as the proximal cause of functional dysphonia (FD). Recently, the term functional dysphonia has been replaced in some clinical circles by diagnostic label muscle tension dysphonia (MTD), which serves to highlight excess, dysregulated, or imbalanced activity of the intrinsic and extrinsic laryngeal muscles as proximal cause of the observed dysphonia. And recent research evidence points to specific personality traits as important contributors to its development and maintenance. However, the origin of this dysregulated laryngeal muscle activity has not been fully elucidated. Further research is needed to better understand the pathogenesis of functional dysphonia, and factors contributing to its successful management.

The origin and growth of laryngology is inseparably linked to the development of endoscopic surgery of the larynx. Phonomicrosurgery is a means of maximally preserving the layered microstructure of the vocal fold, that is, the epithelium and lamina propria. Phonomicrosurgery has developed from convergence of micro laryngoscopic surgical technique theory and the mucosal wave theory of laryngeal sound production. Improvements in technology (i.e., laryngoscopes, handled instruments, and lasers), which in part arise from developments in more frequently performed minimally invasive surgical procedures, will probably facilitate the next generation of procedural innovations. The best methods of optimizing phonosurgical outcomes include making an accurate diagnosis, completing a comprehensive voice evaluation, providing sufficient preoperative therapy, carefully selecting patients to undergo phonomicrosurgical procedures, and requiring sufficient postoperative rest and therapy. Phonomicrosurgery will continue to evolve as a result of the interdependent collaboration of surgeons with voice scientists, speech pathologist, and other voice professionals.

The speech signal has been put into a form suitable for storage and analysis by computer, several different operation can be performed. Filtering, sampling and quantization are the basic operation in digiting a speech signal. The waveform can be displayed, measured and even edited, and spectra can be computed using methods such as the Fast Fourier Transform (FFT), Linear predictive Coding (LPC), Cepstrum and filtering. The digitized signal also can be used to generate spectrograms. The spectrograph provide major advantages to the study of speech. So, author introduces the basic techniques for the acoustic recording, digital signal processing and the principles of spectrum and spectrogram.

The laws of physics that govern actions of all moving bodies apply to sound. Because sound and all acoustic conditions consistently behave as described by the law of physics, we are able to predict and analyze the nature of a sound and its interaction. A fundamental understanding of the nature of the sound and terms used to describe it is essential to comprehend the language of otolaryngologists, audiologists, music acousticians, and engineers. Moreover, studying the basic physics of the sound helps one recognize complexities and potential pitfalls in measuring describing sound. We will talk about the structure of sound and its components, and we will see the various qualities of sound that make it interesting and useful to understand.

The term "phonosurgery," coined in the early 1960s, refers to surgical procedures that maintain, restore, or enhance the human voice. Phonosurgery includes phonomicrosurgery (endoscopic microsurgery of the vocal folds), laryngoplastic phonosurgery (open-neck surgery that restructures the cartilaginous framework of the larynx and the soft tissues), laryngeal injection (injection of medications as well as synthetic and organic biologic substances), and reinnervation of the larynx. Phonomicrosurgery is a means of maximally preserving the layered microstructure of the vocal fold, that is, the epithelium and lamina propria. The purpose of the surgery is usually to improve the vibratory characteristics of the layered microstructure of the vocal folds. Phonomicrosurgery has developed from convergence of microlaryngoscopic surgical technique theory and the mucosal wave theory of laryngeal sound production. Improvements in technology (i.e., laryngoscopes, handled instruments, and lasers), which in part arise from developments in more frequently performed minimally invasive surgical procedures, will probably facilitate the next generation of procedural innovations. The best methods of optimizing phonosurgical outcomes include making an accurate diagnosis, completing a comprehensive voice evaluation, providing sufficient preoperative therapy, carefully selecting patients to undergo phonomicrosurgical procedures, and requiring sufficient postoperative rest and therapy. Phonomicrosurgery will continue to evolve as a result of the interdependent collaboration of surgeons with voice scientists, speech pathologist, and other voice professionals.

Granular cell tumor is an uncommon lesion that was first described by Abrikossoff in 1926. It is usually benign tumor that can occur in any parts of the body. The most common region of granular cell tumor is the head and neck, accounting for approximately 30 to 50 percent of all lesions, with the tongue as the single most common site of origin. The larynx is uncommon location, accounting for approximately 3 to 10 percent of the reported case. Herein we report a case of a 41-year-old man with laryngeal granular cell tumor who was successfully treated, especially showing well improvements in his voice after the operation. In addition, a brief discussion of the current literatures regarding the typical features of the tumor are also presented.

The anatomy of the voice is not limited to the region of the larynx. Practically all body systems affect the voice. The larynx receives the greatest attention because it is the most sensitive and expressive component of the vocal mechanism, but anatomic interactions throughout the singer's body must be considered in making the singing voice. The physiology of voice production is exceedingly complex. The voice requires interactions among the power source, the oscillator, and the resonator. The review of functional anatomy and physiology in vocal technique would provide information on the terminology, components, and workings of the voice to permit an understanding of practical, every clinical problems and their solutions. The otolaryngologist, speech language pathologist, singing or acting teacher, singer, and actor would have benefit greatly from more extensive study of voice science.

글로벌 프랜차이즈 제휴관계에서 갈등행동에 관한 질적 연구

진성민(제1저자) ( Sung Min Jin ),강인원(교신저자) ( In Won Kang ) 한국통상정보학회 2015 통상정보연구 Vol.17 No.4

프랜차이즈 제휴는 기업에게 빠르고 안정적으로 신규 시장에 진출할 수 있게 해주어 국내뿐 아니라 해외시장진출의 방법으로도 그 중요성이 강조되고 있다. 하지만 본사와 가맹원간 불균형적인 힘의 관계로 인하여 크고 작은 갈등이 끊임없이 발생하여 본사와 가맹원 양측에 큰 타격만 남기는 경우가 증가하고 있다. 이에 본 연구는 프랜차이즈 제휴 운영에 있어 효과적인 자원배분을 위한 전략적 대안을 제시하고자 제휴관계에서 본사와 가맹원의 관계적 갈등과 운영적 갈등이 가맹원의 갈등행동에 미치는 상대적인 영향력을 파악하고자 하였다. 검증결과, 관계적 갈등 중에는 목표불일치가 문제해결행동에 가장 커다란 영향력을 발휘하며, 운영적 갈등 중에는 투입자원 불균형이 적극적 공격행동에 가장 큰영향력을 미치는 것으로 나타났다. 특히 프랜차이즈 시스템에 대한 평가 중 인지적 불신보다 정서적불신이 갈등행동에 더욱 강한 영향력을 미치는 것으로 나타나 가맹원이 프랜차이즈 시스템으로 인해손해를 입을 것이라는 우려감을 가지지 않도록 하는 것이 전략적으로 중요하다는 것을 확인할 수 있었다. 마지막으로 국내 브랜드 프랜차이즈에 비해 파트너간 정보교환 시스템이 상대적으로 잘 갖추어진 글로벌 브랜드 프랜차이즈에서는 파트너간 갈등이 적게 발생하고 갈등이 협력적으로 해결되는 것으로 나타나 원활한 의사소통체계를 갖추는 것이 중요하다는 것을 확인하였다. Franchise is a fast and secure mode of market entry that is a becoming popular to firms entering both domestic and foreign markets. However, conflicts that arise from to the asymmetric balance of power between franchiser and franchisee is becoming more frequent. Therefore, to provide a strategic alternatives to enable effective allocation of resources, we analyzed relative effects of relational conflict and operational conflict between franchise alliance partners on franchisees’ conflict behavior. According to the empirical result, among the relational conflict, goal incongruity had the greatest influenced on problem-solving behavior. Among the operational conflict, asymmetric alliance-specific investment had the greatest impact on active-aggressive behavior. Especially, as affective distrust on franchise system had more effect on conflict behavior compare to cognitive distrust, we found that managing affective distrust is strategically important to minimize partner’s concern over the franchise system. Lastly, compared to domestic franchise, global franchise with better information sharing structure experienced less conflicts and managed conflicts more cooperatively, highlighting the importance of inter-partnership communication in franchise alliance.
